Visible crew/equipment: At the end of the episode where everyone is cleaning up, there is a shadow of the boom mic on the wall. (00:29:05)
Continuity mistake: When Basil brings in Lord Melbury's cases, they swap hands between the exterior and interior shots. (00:14:20)
Audio problem: Throughout the episode the picture Basil is distracted from putting up has no glass covering on it. However, when he smashes it at the end you can hear the distinct sound of glass breaking. (00:29:35)
Visible crew/equipment: When the bald hotel guest asks Basil for his drinks and slams his hand on the table, in the next shot a boom mic can be seen briefly as it is pulled away. (00:24:05)
Visible crew/equipment: Near the start of the episode, after the guest has told Basil that he will only be staying until Sunday, Basil walks from the dining room to the office, and the shadow of the camera following Basil can be seen in the reflection of the studio lights in the picture above the Drawing Room door. (00:04:45)
Visible crew/equipment: When Basil asks the family sitting by the window to move, a boom mic can be seen in the top right hand corner. (00:16:05)
Revealing mistake: When Manuel throws the grapefruit at the other guests, you can see the woman closest to the camera react before Manuel throws it. (00:11:00)
Revealing mistake: When Basil sends the grapefruit flying, we see Polly go through the doors to the kitchen. However, if you look closely at the doors as she goes through you will see just a plain wall. Not the kitchen as is seen in other episodes. (00:11:00)
Suggested correction: The sound isn't glass as you can see just as he goes to smash the picture there is no glass on the picture.
